To if the; United States, a resident ofv :Boonville, QneidaCounty, and State of New,

, Beitlrnown that I,- M R DEAN, a'citizen York (whose post-otfiee addressis P. O.

box 272,;lioonville, N. Y), have invented certain new and useful Improvements in Vises, of which the tollow ng s specincaother cylindrical objects, of difierent sizes may be received'and firmly held and readily released without injury to the pipe or other article so received and held. 7,

My improved vise is not only capable of indefinite adjustability to different sizes, but

the limit of closing of the gripping jaws is automatically determined" and secured by the pipe, tube, rod, or other article, itself without any biting or other injurious contact with the material of said pipe or other object.

One accompanying drawings in which Figure 1, is a side elevation.

Figure 2, is a top plan.

Figure 3, is a longitudinal section to dis-v play the eccentrics andthe limiting bar.

Figures 4:, 5, 6, and 7, are detail views of one of thelimiting bars, G, G.

Same letters indicate similar parts in the different figures. a

A is a suitable base upon which the vise is mounted. This vise consists, primarily, of twov revoluble cylinders B, C, mounted respectively on pins 6, b, in the uprights a, a, rising from the base A. 1

The size and shape of cylinders B, O, vary with the number of different sizes of pipes or other articles which are to be treated by the aid of the vise. Obviously, the greater variety of sizes the larger will be the periphery of the cylinders. This periphery is provided with a number of receiving'and gripping depressions, ,D, D, which vary to correspond with the various articles to be received and heldby said vise from the smallest which,'as shown, is l inch to the largest which, as shown, isone inch pipe.

It will be understood that thedepressions D, will be so arranged on the cylinder B, as to register withthe depressions D, on the disk C, when the cylinders are turned size.

form of my invention is shown in the shoot up ordown respectively. I this, I introduce adjustableliniiting bars into position to receive the pipe. -v The zlinders are free to revolve independently, or may be geared together to rotate simultaneously; if preferred. The rear end of the pin 6, is preferably square to enable it .tobeturn'ed by a handle placed thereon, and by. which handle tie cam F, an integral part of, the pin 6, is thrown forward or backward, tobring the disk Gtow a'rd: or .away from the cylinder 13, to-secure' the registeringdepressions." A H The teatures sortar described are all that will be necessary to'enable myimproved grip or release of the pipe held between the vise to receive and hold pipes of the desired Q In such case the operation will consist of turning the two cylinders ,so that the proper sized 'depressionswill register their lower edges while their upper edges are far enough apart. to receive the pipe from above; the pipe. will be placed in the mouth thus formed by the openings and allowed to drop on to the limiting bars G, G and then the cylinder C will be thrown into gripping contact to hold the pipe. After the work desired has beendo-ne on the pipe, the jaws will be opened by a reverse motion of the cam F, which will release the pipe. In this use of my improved adjustable vise, however, the gripping depressions would not secure 'a perfect hold upon the-pipe unless the pipe was exactly centered before it was gripped- It the pipe in falling lie a little above or below the center, the pressure would cause the pipe to To avoid G G.' which are loosely hung on the two eccentrics H, I, of the cylinders B, C, respectively. Each eccentric is so shaped that its limiting. bar rises and. falls to levels which correspond to the sizes of the differentdepressionsfD, D. JV hen properly ad justed, the limiting bar alwaysoccupies a position sufliciently below'the opening between the lower edges of the registering dcpressionsthat-the pipe to be held, on conion tacting with said bar, assumes a position with its center slightly below thecenter'of pins 6, b, and therefore all'tendency to shoot upward as the gripping takes place is counteracted and aperfect hold 1S secured on the pipe.

To guard against breakage which might result to the limiting bar, it the cylinders B, C, should/not turn in unison, I'ha've Y made What in my earlier single limiting bar, into machine Was two pieces or halves, G, G, each of Which is'a' duplicate c of theother, and consistsef air eccentric strap and, a tongue with ari'elevated portion to act as a r-est for the articles gripped.
